Next-generation firewalls offer greater network protection than traditional firewalls.
FREMONT, CA: Compared to conventional firewalls, Next-Generation Firewall (NGFW) has unique characteristics. The business can gain additional advantages by utilizing NGFW and its advanced features. NGFW provides several capabilities traditional firewalls lack, such as preventing malware from entering a network and dealing with Advanced Persistent Threats (APTs). Combining the functions of antivirus, firewall, and other security applications into a single solution makes NGFW a viable option for businesses seeking to improve their security.

The Advantages of an NGFW
Multiple Protection Layers: Antivirus software that comes with preinstalled devices is insufficient in today's digital age. Businesses require numerous layers of protection to thwart cyberattacks. Unlike a traditional firewall, which provides a single layer of protection by blocking access through ports using information from layer 4, an NGFW inspects traffic from OSI layers 2 through 7. This provides businesses with greater visibility into network activity, including who, when, and from where malicious websites are accessed.
Multi-Functional: NGFWs offer all the advantages of a conventional firewall but go a step further by incorporating integrated intrusion detection systems (IDS) and intrusion protection systems (IPS), which can assist businesses in improving packet-content filtering. They also detect regular user behavior and any deviations from it, protecting the network from intelligent attacks and alerting companies if any devices connected to their network are engaging in unusual activity.
Moreover, the IDS/IPS continually updates its database of malware and cyberattacks. As cyber criminals create new viruses, NGFW will constantly learn and develop strategies to combat them to provide companies with enhanced protection.
Threat Security: Typically, traditional firewalls do not include antivirus and malware protection. Viruses and malware can pass through a conventional firewall, so companies need separate antivirus software. On the other hand, any NGFW worth it's salt will include antivirus software that scans all uploaded and downloaded files and data. Additionally, the software will examine checksums, perform a signature-based analysis, and scan the file for malicious code.
Geolocation: Businesses can restrict network access by using next-generation firewalls. Geolocation enables the creation of NAT (Network Address Translation) rules, which can be used to direct traffic from various regions to distinct servers. Due to the dynamic nature of IP address allocations, an NGFW must constantly evolve and adapt to new requirements.
VPN Support: Organizational networks may be vulnerable to cybercriminals due to the frequent lockdowns in Australia that force employees to work from home and the regular use of personal devices such as smartphones and tablets. A networked device connected to an unsecured internet access point may be susceptible to phishing, hacking, and malware. An NGFW enables the creation of VPNs (Virtual Private Networks) that are more secure, monitored, and protected.
